It is original and rather good condition. It was all white from the factory, yet has "Spec" on the paint code.
There were round Decals on the doors, so I assume that maybe they were put on from the factory. When I pulled the gas tank, it had a tag on it from the Chevy garage at Ft. Hood, up near there.
On the passenger side of the windshield on the inside, is a sticker that has me wondering, it reads:
Department of (some numbers)
Consumer Affairs
Approved
no - system
I'm curious if anyone from up that way, may have some idea of what this may have been for? The round decals on the doors are gone, but you can sort of see the image. Unfortunately, I don't have a place to post them for you to see them.
Thank you

Things like cars that came equipted with dual carbs
were exempt also.I think that was in the early '70's.
Were the decals on the outside of the doors?

I have a 66 Rambler which sold new in CA and has an air injection pump on it. There was a requirement beginning in 1966 to install emission control devices which included crankcase ventilation systems and the carb had to be calibrated for emissions I think. I'm not sure about the carb, but there was a requirement for compliance sticker under the hood when the emissions mods were made. I think cars and light trucks imported into California had to conform for a few years. Now they don't since Federal standards have become stricter anyway. So that sticker on your windshield could have stated that the truck has beem modified to conform or that it had been exempted for some reason like 60 Anglia said.

They were about 18" in Dia.
The Burb has a 292 with a 4 speed, and it also has the smog pump and all the goodies still on it. I figure I may as well leave it on, not like I plan to race it or any thing. I would have to double check, but I believe it lists the smog equipment on the build sheet in the glove box.
It seems kind of strange that it has the "Spec" on the paint tag, since it is all white, unless it was military or a fleet vehicle.
Thanks again for the help guys. | | | | | Joined: Aug 2010 Posts: 66 Shop Shark | | Shop Shark Joined: Aug 2010 Posts: 66 | It could have been a California State vehicle,
or been owned by a city.

During the early, retro-fitting years of smog devices many vehicles had to be fitted with system that decreased nitrous oxide (NOX) emissions. Seems like it had something to do with limiting ignition advance. I do remember that unlike the PCV systems, the NOX systems decreased performance.
